  • Take one butt connector and add it to the stripped part.
  • Choose any suitable dies and use the tool on the connector so that it crimps into place. You may need a heat source as well.
  • Remove it and check whether it has been crimped properly. While it is possible to crimp again, we recommend that you be careful and aim at getting it right the first time itself. Repeated crimping may result in a shabby job.
